Rockstar is working to transition the online components of Red Dead Redemption, GTA4 and Max Payne 3 in response to GameSpy's server shutdown.
Core online gameplay will be saved for these titles, although the servers for older Rockstar games will be shut down when GameSpy ceases operating on 31st May.
Grand Theft Auto 5 is unaffected, Rockstar assured in a new FAQ post.
But some features in the company's other biggest games will be lost during the move.
Red Dead Redemption's online multiplayer will remain operational, but its Social Club stat tracking, leaderboards and in-game Social Club services will not survive the move. In-game multiplayer leaderboards will also be removed for the game's PlayStation 3 version.
Grand Theft Auto 4's online multiplayer will also stay, although again, Social Club stat tracking, leaderboards, and in-game leaders on PlayStation 3 will be removed.
Max Payne 3's online gameplay will survive - except on Mac, where it will be removed. Social Club stat tracking, leaderboards and in-game leaderboards will be unaffected.
Now onto the older titles. Midnight Club Los Angeles will have its PlayStation 3 online multiplayer shut down, although other versions will survive. Social Club features, account linking and the in-game Rate My Ride and Driving Test unlocks will also be disabled.
Grand Theft Auto: Chinatown Wars will see all Social Club mini-games, stat tracking and content unlocks removed across DS and PSP versions.
Rhythm title Beaterator will similarly see all Social Club features removed, and its track upload/download feature disabled.
Finally, Midnight Club 3: Dub Edition will also have its online multiplayer mode and in-game leaderboards switched off.
GameSpy's decision to close its long-running multiplayer serves - used in hundreds of games across multiple companies - has had far-reaching consequences. Here's a round-up of the titles we know to be affected so far.
